The Blender Foundation and online developer community released Blender 2.77 with more than 100 of bug fixes and improvements; honestly, this is a quite nice number of changes. Between the most noticeable changes belongs a new Subsurface Scattering algorithm - (Christensen-Burley). The new added Subsurface Scattering algorithm (Christensen-Burley), preserves details much better than the Cubic/Gaussian falloffs and It is the new default falloff for the SSS shader. The new version include GPU support for Smoke/Fire, Point Density (3D textures) and optimize memory usage and performance of Subsurface Scattering on the GPU which at the end results in up to 3x faster SSS renders! As a result of the new changes in GPU rendering, the developers decided to remove the experimental CUDA kernel and make Subsurface Scattering and Correlated Multi-jittered sampling regular features. The user interface and therefore also the workflow was improved too and adds stroke sculpting support to the Grease Pencil, implements OpenVDB caching for both volumetric and smoke simulations, and it now offers a redesigned progress bar, thus completing the design overhaul.

Moreover, some improvements was given also to the modeling and the decimate modifier is now symmetry aware with support for multi-line text in frame nodes, metadata display, render stamps, and tooltips, a new Edit-mode Boolean tool was introduced for fast editing. Other small improvements: triangulate & poke, grid-fill non uniform grids, hole support for intersect tool, split-by-edges tool.
